T all tuhom z't may concern: Be it known that I, MERVIN B. CANNON,

a citizen of the United States, residing at Cincinnati in the county of Hamilton and State of hio, have invented certain new and useful Improvements in Packaging Mat-- chines, of which the following is a specificationh My invention relates to machines for making special packages; and the objects of my invention are to combine in a single package a. plurality of objects, one of which forms the wrapper of'the package, and

preferably to make the package very compact and smooth, so as to be readily dispensed in a suitable vending machine. Other objects will appear in the course of the ensuing description.

I attain these objects by the mechanism illustrated, for example, in the accompanying drawings, in WhlCh Figure 1 is a side elevation, with parts in vertical lengthwise section, of a machine embodying my invention;

In practlce, I prefer, for the particular purpose of my invention as herein exemplitied, to wrap together two pieces of towel material, preferably crepe-paper of aweight Mil . suitable for the purpose, and a single small the illustrations and description herein.

For supplying the sheet material in web form, a suitable reel or the like is provided;

and just before entering the machine the webs or web may pass through suitable means for printing or otherwise marking thereon or'therein any display-matter, advertising or other kin which it may be desirable to have appear thereon. Also, suitable guiding and supporting means, such as idler rollers, ma receive the webs or web before entering t e machine, to facilitate renewal of the supply without stopping the machine. Such apparatus as any of these are well known, and require no illustration or detailed description herein.

The machine comprises the pedestal 1 of box-like formation, extending from. the left or feed end for the major part of the length of the machine. The first-creasing roll standards 2 are supported on this pedestal 1 at opposite sides thereof, near the left end. Each standard 2 has upright guides 3 near its top, with the lower creasing roll 4 journaled between their bottoms, preferably in ball-bearings 5. In each pair of guides is the bearing 'block' 6, in which blocks is journaled the top first-creasing roll 7. against the lower roll 4. A helical spring 8 is compressed between the top of each bearing block 6 and a bar 9 also guided in the respective guides 3 and held down by an adjusting screw 10 in a. cap 11 bolted to the guide tops. The upper and lower rolls .7 and 4 have spur ears 12 and 13, respectively, concentrically iixed on them and meshin together; and the upper roll 7 also has sin'nlarly fixed to it, outside the front standard 2, a sprocket wheel 14. A driving shaft 15 is journaled transversely in the pedestal 2 below the standards 2, with a sprocket wheel 16 fixed on it at the front; and a sprocket chain 17 passes around the wheels 14 and 17.

The upper roll 7 has annular flanges 18 at its ends, and'the lower roll has end offsets 19 receiving the flanges 18. Also, the upper roll 7 has, spaced substantially equally from each other and from the flanges 18, annular ridges 20; and has adjacent to the middle ridge 20, at each side thereof, a depression 20*, entirely around the roll and extending a considerable distance toward the end of the roll (Fig. 3). The lower roll has annular grooves 21 receiving theuppeiroll ridges 20; and the depressions 20 leave empty spaces between the rolls, allowing the sheet material to stretch the required degree to form the middle crease under the action of the cooperating middle groove 21 and middle ridge 20, as is readily possible with such materials as towels and the like are made of.

Crepe tissue is especially susceptible to this on account ofits wrinkly condition.

A proper distance to the rightof the just described mechanism is another pair of standards 22, transversely spaced, and a shorter standard 23 between the standards 22, at the. middle of the pedestal 1. A yoke 24 is fixed across on the tops of the standards 22, with an arm 25 depending from its middle. A stud 26 projects to the right from the lower end part of this arm, and on this stud are four arms 27 projecting diagonally upward and downward with equal spacing around the stud 26, forming a spider which supports the surrounding hollow core 28, of

a cross-section which is rectangular, with substantially equal sides, at the left or feed end, and with its sides running diagonally so that two of its corners are in vertical and the other two of its corners are in horizontal alinement. This cross-section continues for a very short distance, then merging into one that gradually changes to a very much flattened' and correspondingly widened quadrangle. Surrounding this core, with its interior sides spaced sufliciently from corre= sponding sides of the core, are the two sections of the shaping-box, the rear section 29 having at its top two shackles 30 hinged to drop into forks 31 at the top of the front section 32, and both sections being concencentrically hinged on an axis lengthwise of the machine, constituted by a pin 33 with its feed-end supported by the middle shorter standard 23 and a similar standard 34' at the delivery-end thereof. These box-sections 29 and 32 conform to the core 28 where they surround it, but terminate a short distance back from the delivery-end thereof; while at the feed end, these sections have lips 35 with their tops properly converging and their lateral sides properly diverging toward the feed end of the machine. The top of the lip is notched, by virtue of proper recesses in the sections 29 and 32, to fit around the depending arm 25.

(lose to the delivery end of the mechanism just described, is another pair of standias wheel on the upper roll shaft; this latter having a chain around it, which chain passes around the driving sprocket wheel on a shaft transversely journaled in the pedestal below the standards. All of these parts being like those of the first \set of rolls, they are correspondingly numbered. But this second set of'rolls are not so wide as the first set. The lower roll 36 has the oifsets'19' in its ends and the upper roll 37 has the flanges 18' on its ends, entering the offsets, the same as the first rolls. The upper roll 37 has a single annular 1'idge20-aro1md its middle; ,enterin g a single annular groove 21' around the middle of the lower roll 36. The coaction and adjustability of these rolls. 36 and 37, having the same mounting and driving means, are like those of the first rolls 4 and 7.

A proper distance to the .right of the roll mechanism just described is a bench 38 crosswise of the pedestal 1 with uprights 39 at its ends at front and rear of the machine, with a top-piece 4O fixed across on the tops of these uprights. At the rear is the rear final flattening roll 41, journaled, on a vertical axis, in the top of the bench 38 below and the top-piece 40 above, preferably in ball-bearings 42 therein. The front final flattening roll 43 is journaled in blocks 44 slidable from front to rear in guides formed at the sides of suitable openings in the bench-top and top-piece, respectively; these blocks being pressed rearwardlyby helical springs 45 compressed between the blocks and screw-plugs 46 in the bench-top and The rear roll 41 has offsets 47 and the front roll has flanges 48 entering the offsets. 47,. at the upper and lower ends of the rolls. These rolls have no ridges nor grooves around them.

A pr'oper distance to the right of this mechanism just described is a frame made up of sides 49 standing upright at front and rear of the pedestal 1. The left-hand or feed-end parts of these sides are similar to the standards 2 of the first-creasing and sec- -ond-creasing mechanisms before described; and the mountings and driving elements of the cutter-feeding rolls 50 and 51 in these frame-sides 49 are the same as in those mechanisms. These parts are therefore correspondingly numbered, as are also the sprocket chain and its wheel fixed on the transverse shaft in the pedestal 1 below this frame, for driving this cutter-feeding mechanism.

= The frame sides 49. in their parts to the right of the standards, are not so high as the standards, and at their right-hand ends. on their tops, they hate the cutter-rotor 52 journaled in them, preferably in ball-bearings 53, which rotor has, outside its rear bearing, a spur gear 54 fixed concentrically to it. Below and to the left of the rotor,

two idler gears 55 and 56 are journaled on with the gear 13" of the lower cutter-fee ing roll 50. The cutter-rotor 52 has a projection 52' with one side flat and the other receding down to the normal convex surface of the rotor; and on the fiat side is mounted 1 the blade 57 by means of clamp-screws 58 through slots 58' in the blade and screwed into the projection 52'. These slots, running back from the cutting edge, permit the blade to be adjusted inwardly or outwardly substantially radially of the rotor. To permit this adjustment to be nicely made, adj usting screws 59 are threaded approximately diametrically through the rotor against the back of the blade. To cooperate with the rotor blade 57 a fixed blade 60 is mounted on a cross-bar 61 by means of clamp-screws62 through slots 63 in the blade and screwed into the cross-bar. These slots, running back from the cutting edge, permit the fixed blade '60 to be adjusted toward or from the rotor blade 57. This adjustment is made with keys 64 fitting between the blade 60 and inclines 65 on the cross-bar 61 and pushed in from the front and rear sides, respectively, by adjusting screws 66 threaded through small brackets 67 screwed to lugs on the tops of the frame. The rotor and fixed blade are positioned at such a height that the upper surface of the fixed blade, located between the rotor 52 and the cutter-feeding rolls 50 and 51, is slightly below a horizontal tangent to the meeting rolls 50 and 51.

Preferably, all of the rolls 7, 4, 36, 37, 41, 43, 50 and 51 are suitably scored, striated or roughened, to permit them toproperly grip and feed the web between the rolls of the respective pairs.

The folding-table 68 extends from under the cutter-rotor 52 past the delivery end of the pedestal 1; being formed of two parts 68' and 68 bolted to a back plate 69 mounted on the pedestal top at the rear. vThe top of this table 68, in both parts 68 and 68". isfiat, and set a substantial distance down from the bottom of the cutter-rotor 52: while the adjacent ends of the two parts 68' and 68" are, respectivey, concave and convex on concentric curves, the center of which is the axis of a bearing in a bracket 70 fixed on a delivery-end extension of the folding-table. These concentric ends of the parts 68 and 68 are spaced slightly more than the thickness of the folding-bar 71,

front of the folding-table 68 and mounted on a base plate 1 on which the entire machine, including the pedestal 1, is mounted. To the rear of the bracket 70 a short arm 76 is fixed on the folding-shaft 74, extending up at a proper angle from the folding-arm 72, and having pivoted to its free end a link 77 that extends toward the feed-end and is pivoted to a rocker 78 fulcruined in a bracket to the rear of the folding-table 68. This rocker 78 is of a width from front to rear to bring another link 79 pivoted to it coaxially with the pivoting of the link 7.7, back of a slotted lever 80 fulcrumed below in a bracket to the rear of the folding-table vertically under the axis of the cutter-rotor 52, to the upper end part of which lever the link 79 is pivoted. A wrist 81 is fixed in the cutter-rotor gear 54 and extends back through the slot 82 in the lever 80. This slot has its middle part arcuate so that, during the cut- .ting period of the cutter-rotor rotation, no

' cutting.

are raised cutting,

motion is imparted to the lever 80; but the upper and lower end parts of this slot receive the wrist with a bearing fit, so that the remainder of the rotation of the rotor oscil lates the lever 80 through equal angles from the vertical. The wrist is so positioned in the gear 54 that this oscillation is toward the delivery end during the-half of this remainder prior to cutting, and in the opposite direction ,during the other half, after the Thus the folding-arm and bar 71 68 prior to cutting, and then, just after the start down along the arc-shaped slot between the folding-table parts 68 and 68", stopping after the folding-bar 71 has passed from under the folding-table upper part 68" at the delivery end of the slot.

During this downward sweep of the foldingarm and bar 71, the folding-arm 72 is at the inner end of the travel it has on the square part of the folding-shaft 74, to carry the folding-bar 71 in the arc-shaped slot as just described. The folding-bar 71 is'preferably of wedge-shaped cross-section, with the narrow edge downward. This edge is rounded and smooth, to avoidcutting of the material folded thereby.

Another shorter post 83 is mounted on the base-plate 1' shortly .to the rear of the post 75, and a cam 84 is journaled in these posts '75 and 83. This cam 84 is cylindrical as shown, except in Figs. 21, 22 and 23. where a face-cam is shown, either form being suitable. Either cam has its slot or face, as the case may be, so shaped that the lever 85, having trunnions 85' with rollers in the cam slot, or, as in Fig. 21, the roller-finger of the lever 85" on the cam face, is held stationary and inclined over toward the folding-table 68 (Fig. 20) or approximately vertical, away from the folding-table. as shown by dotted lines in Fig. 20 or the full lines in Fig. 21;

above the top of the folding-table and so the lever is shifted from one of these posltions-to the other. With the face cam of-Fig.- 21, the lever 85" is pulied away from the folding-table 68 by the spring 84 attached to the lever and to the post 7 5? The fulcrum of the lever 85 or 85 is in two arms 86 fixed to opposite sides of the post sprocket wheel 89 in front of the post 75, the

folding-bar 71 is withdrawn forwardly en.- tirely from the folding table 68 during the upward swing of the arm, but is shifted backwardly over the table just before it starts to swing downward along the. slot between the folding-table parts 68 and 68" as before described.

At the entrance'to the curved slot, in the folding-table top,-are rollers 90, at opposite sides of the slot, extending across the table from front to rear. Also, preferably, this folding-table 68 has (Fig. 5) a ledge 91 projecting up throughout its length along its rear side; and front ledges 91' and91" running 'to the left and right ends, respectively,

from'the curved slot on the front side.

Mounted on the folding-table part 68" above the exit of the curved slot, is a bracket- 92 with arms 93 pivoted on its opposite sides, at front and rear, which arms have a roller 94 journaled in their'free ends and are yieldably held down by springs 95 coiled around the pivot pinof the rms with their opposite ends engaging the bracket back and the arm upper edges, respectively.

This roller 94 is thus yieldably held down. The clip-table 96 extends under the foldingtable lower part 68' and its upper surface curves down from v and is concentric with- .the curve of thatpart.

This clip-table 96 extends from the end of the. lower folding-table part 68 some distance toward the delivery and of themachine. It has a longitudinal slot 97in its middle; and near opposite ends, in its sides, has suitable bearings 98 on which are journaled sprocket-wheels 99, .with a sprocket chain 100 around them under the slot 97.

At each end of the slot 97 -is a widevrecess 101 through the clip-table top. At equal intervals along the chain 100 are the lower clip-jaws 102 straddling and fixed to a link" of the chain, and the upper clip-jaws 103 straddling these and piw'oted on an elongated pin 104 in one of the link junctions;

Both lower and upper jaws 102 and 103 are extended laterally to front and rear of the
